Question

这是模型。我创建了自己的用户模型

class Profile(models.Model):
    user = models.OneToOneField(User)
    favorite_food = models.CharField(max_length=100)

    def set_password(self, raw_password):
        self.user.set_password(raw_password)

以下是观点：

class UserFormView(View):
    form_class = UserForm
    template_name = 'templates/core/profile_form.html'

    def get(self, request):
        form = self.form_class(None)
        return render(request, self.template_name, {'form': form})

    def post(self, request):
        form = self.form_class(request.POST)

        if form.is_valid():

            user = form.save(commit=False)

            username = form.cleaned_data['username']
            password = form.cleaned_data['password']

            user.set_password(password)
            user.save()

        return render(request, self.template_name, {'form': form})

这是UserForm

class UserForm(forms.ModelForm):
    username = forms.CharField(max_length=10)
    password = forms.CharField(widget=forms.PasswordInput)

    class Meta:
        model = Profile
        fields = ['username', 'password', 'favorite_food']

这里似乎有什么问题？它还说Profile has no user我尝试将其更改为AbstractUser但是，它还显示有关反向访问器的错误

尝试从表单中排除用户并将save方法添加到表单中：

    class ProfileForm(forms.ModelForm):
        username = forms.CharField(max_length=10)
        password = forms.CharField(widget=forms.PasswordInput)

        class Meta:
            model = Profile
            fields = ['username', 'password', 'favorite_food']
            exclude = ['user']

        def save(self, user = None, force_insert=False, force_update=False, commit=False):

            username = self.cleaned_data['username']
            password = self.cleaned_data['password']

            profile = super(ProfileForm, self).save(commit=commit)
            if user:
                profile.user = user
                profile.set_password(password)

            profile.save()
            return profile

在你看来：

def post(self, request):
    form = self.form_class(request.POST)

    if form.is_valid():
        profile = form.save(user = request.user, commit=False)
